Strong and Electro-Weak Supersymmetric Corrections to Single Top Processes at the Large Hadron Collider

Abstract

We present the one-loop corrections originating from Quantum Chromo-Dynamics (QCD) and Electro-Weak (EW) interactions of Supersymmetric (SUSY) origin within the Minimal Supersymmetric Standard Model (MSSM) to the single-top processes bq -> tq' and qbar q' -> tbar b. We illustrate their impact onto top quark observables accessible at the Large Hadron Collider (LHC) in the 't+jet' final state, such as total cross section, several differential distributions and left-right plus forward-backward asymmetries. We find that in many instances these effects can be observable for planned LHC energies and luminosities, quite large as well as rather sensitive to several MSSM parameters.
